I would end all payroll tax. No income tax for the first $200,000 earned, a flat rate above it, and then institute a value-added sales tax.
The middle and lower classes would be given more income to spend and increased consumption. The government then cashes in on consumption. The government then re-cashes in the consumption when it goes into the salaries of 200k+ earnings..
Of course, I know very little and this is probably a dumb idea. But if I were dictator I wouldn't give a crap.
I like this idea. I'm also a big fan of a VAT.
